SCREEN-DOOR.

SPECIFICATION forming part of Letters Patent N' o. 443,448, dated December 23, 1890.

Application iiled May '7, 1890. Serial No. 350,942. (No model.)

. citizen of the United States, and a resident of Ripon, in the county of Fond du Lac and State of Wisconsin, have invented certain new and useful Improvements in Screen-Doors; and I do hereby declare that the following is a full,

clear, and exact description of the invention,

which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain improvements upon the invention for which Letters Patent Were granted to me July l2, 1887, No. 366,489.

The invention therein contained consisted,

essentially, in a screen-door frame adapted to receive storm-panels upon one side, in combination with strips of grooved molding secured upon the other side of said frame corresponding with the rails and mullions thereof, and storm-door panels secured Wit-hin said grooves, the object being to permit the panels to be readily inserted and the door convertedvfrom a screen to a storm door.

The above construction, While very effective for the purpose for which it is designed, is objectionable in sonic respects, principally upon the grounds of the cost or expense, and the object of the present invention is to simplify the construction and provide a screendoor which can be readily converted into a storm-door, and which may be furnished vat but a comparatively small expense over the ordinary screen-doors in common use.

The invention consists in the combination, with a screen-door frame adapted to receive storm-panels upon one side, of strips of molding corresponding with the rails and mullions of the frameand interlocking with each other and with the inner sides of the frame, as hereinafter more .fully described.

In-the accompanying drawings, Figure 1 is an elevation of the inside of a screen-door which is provided with my improvements. Fig. 2 is alongitudinal vertical section taken on the line cc as, Fig. 1.

In the said drawings, the referencen umeral 1 indicates the frame of a screen-door, and 2 indicates the Wire covering-screen which covers the spaces into which said frame is divided, as shown by its middle rail 3 and Inullions 4. Both sides of the middle rail and the mullions may be formed or provided With grooves on their under edges, as also the inner sides of the side rails of the frame, to

permit of the storm-panels being placed uponthat side of the frame, as fully set forth in Letters Patent granted to me April 6, 1886, No. 339,567. Secured upon the other side ot' the screen-frame are the strips of molding 5, which are preferably provided with grooves 6 to receive the outer edges of the panels. They may,however, be made Without grooves or plain, if desired.

The numerals 7 and 8 designate the removable interlocking retaining-strips by means of which the panels are retained in place.

7 designates the cross-strip, and 8 8 the vertical strips, corresponding to the crossrails and mullions of the screen-frame. These strips may be grooved to receive the edges of the panels, or they may be made plain or without grooves, as desired, they performing their function equally Well in either case. At the center of the cross-rail upon each side is a projection or lug 9, Which fits over the inner end of each vertical strip 8, which is recessed or cut away at 10 for such purpose, whereby said strips 8 are secured in place. The outer ends of the cross and vertical strips are held in place by means of turn-buttons or Wires ll, secured to the screen-frame and capable of being turned in and out of contact with said strips so as to hold or release them.

It is obvious that instead of the lug 9 I may recess the under side of the cross-strip and out away the end of the vertical strips so as to lenter and be held in said recesses.

From the above description the manner of applying myinvention Will be readily understood. When it is desiredV to convert the screen-door into a storm-door, the cross-strip 7 and the vertical strips 8 8 are removed, and the panels 12, which are preferably composed of some thin pliable material, so that the ends may be sprung into the grooves, as fully set forth in Letters Patent granted to me July 12, 1887, No. 366,489, are placed upon the Wire-screen with their outer edges resting IOO in the grooves o' ol` the molding' llle Crossl trip 7 is then inserted in position. The vertical strips are then introduced. .t5 before stated, the cross and vertical strips ma)v be `g'rooved to receive the edges of the panelfs', or they may he made plain, as ma)v he found most convenient or desirable.

lhe advantages ol' the invention will he readily understood. It will be seen that the Storm-panels ean he inserted and seenred in position iu a few moments, and will thus transform the screen-door into astornrdoor,

ett'eetually preventing' the entrance of rain, 1

wind, or snow,aud at the same time will proteet the sereen from injury or damage.

Having thus described my invention7 what l claim, and desire to Secure hy VLetters latent of the United States, is-

l. The combination, with a Sereeirdoor frame provided with detachable cross-strips and. vertieal strips and adapted to receive stormq'ianels upon one side, of the rails and t mullions ujon the opposite side correspond in;r with the Strips, Said strips interlockinfbr l with each other and with the doo1fraine,sub stantially as and for the purpose set forth.

i. The combination, with a screen-door trame and panels,of the erosSstrip 7,11avin.;r lugs 9, the vertical strips S S, and fastening` device ill for removably Securing Said strip l to the screen-frames, Subrtnntiallwv as deserihed.

ln testimonvY that I elaim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
